I dont know much about head cc so I am wanting to know what the best I should look for I also would like to know How good are 76cc heads?
thanks

 

the volume of the combustion chamber will affect your compression ration. for example a engine with 64 cc combstion chamber cylinder head will have higher compression ration than the same engine with 74 cc combustion chamber. when it come to head selection, combination is everything, you need to select the right intake flow speed(go from around 160cc all the way to 230cc)
big isn't always better, for a stout 383 street engine 190 cc intake flow is good, but a 190 cc intake on a 350 is marginal too much. hope this clear up few thing
